Scanrec Scanner Recorder - Scanner Recorder (Scanrec) is a free audio recorder that is primarily designed to record speech. It has a VOX control that allows the user to save disk space when no sound is present in the signal. Since FM communications has such an effective squelch, the recorder works best with FM. HF ham bands and World Band radio have such a poor signal to noise ratio that the VOX gate on Scanrec might not be very easy to set.

Vox Recorder  ^pop - Vox Recorder is a Windows utility wich allows recording sound from an audio source only when an audio signal is present; its main purpose is to avoid the recording of the silence eventually present at the input. Vox Recorder has been designed in particular for radio-scanner hobbists.

Voice Shaper - Voice Shaper is a freeware windows speech pre-processor for SSB transceivers. It receives the voice signal from the microphone connected to the soundcard, and sends the processed audio back to the soundcard in real time by Alex Shovkoplyas, VE3NEA

MT63 Terminal - MT63 soundcard program for Windows by IZ8BLY

WinMSDSP 2000 - Shareware program to receive and transmit high speed CW (morse code) used in MS (amateur radio communication mode) with MS Windows 95/98 and sound card.

CW Player  ^pop - Simple freeware program generates Morse caracters and Q codes. It needs a sound card and Win95.

WinWarbler - A free soundcard application supporting PSK31, PSK63, RTTY, CW, and Phone operation. It can decode all PSK QSOs within a 4 KHz segment, maintaining a sorted list of heard callsigns; it can simultaneously decode RTTY via soundcard and an external modem, generates CW directly or via WinKey, and includes a voice keyer. WinWarbler interoperates with the free Commander, DXKeeper, and SpotCollector for transceiver control, logging, and spotting.

AGW Packet Driver - SV2AGW packet radio driver, runs TCP/IP protocol over radio, support windows 95/98/NT and several devices like baycom and, E5DXL 9600 G3RUH compatible modems, DRSI and Sound cards by SV2AGW George Rossopoulos.

Ionospheric Simulator - This program simulates a HF link, using sound card and WIN95 by Michael Keller, DL6iAK

PathSim - PathSim is a Windows program that can be used to simulate radio propagation paths using a soundcard and/or wave files as the source and destination.

Zakanaka  ^pop - A digital mode decoding and terminal program that uses no terminal unit, terminal node controller, or multimode hardware. It does all its decoding using the sound card inside the computer, and it can interface with a radio using a COM port. Zakanaka is an extremely cost-effective way of operating PSK31 and RTTY

Zelscope  ^pop - Zelscope is a Windows software that converts your PC into a dual-trace storage oscilloscope and spectrum analyzer. It uses your computer's sound card as analog-to-digital converter, presenting a real-time waveform or spectrum of the signal - which can be music, speech, or output from an electronic circuit.

Spectra - Accurate spectrum analyzer in the range 0 - 2500 Hz, makes an accurate FFT analysis of an audio signal coming from the soundcard

FFTDSP  ^pop - FFTDSP is a PC program which can detect weak radio signals in real time. Uses the PC's soundcard and advanced signal processing techniques, extracts and displays weak signals from the receiver audio.

WXSat - WXSat for Windows 3.1/95/NT, decodes the signals in the APT format from NOAA, Meteor, Okean, Resurs, Meteosat and GOES Satellites (AM) with a Soundcard. WXSat can decode also FM-Fax for decoding facsimile-signals transmitting via shortwave
